PNPP 是用于 ELISA 和常规分光光度测定的碱性和酸性磷酸酶的非蛋白质显色底物。
产品描述
PNPP is a non-proteinaceous chromogenic substrate for alkaline and acid phosphatases used in ELISA and conventional spectrophotometric assays.
体外活性
Phosphatases catalyze the hydrolysis of PNPP liberating inorganic phosphate and the conjugate base of para-nitrophenol (pNP) and the resulting phenolate is yellow, with a maximal absorption at 405 nm[1].
